hi, I'm new here so bear with me. This spring, I removed my woodburning insert(really old with no info about manufacturer) for major cleaning and some chimney repairs. I removed two 110 volt motors, a 110volt thermostat, and one 110 volt on/off switch from the stove(thinking I could remember how they were) wrong. Seems the way I thought was right the fans only run at 53 volts, half speed. Could anyone draw me a diagram of how to wire this thing up? again, it has 2 blower motors, 1 thermostat and 1 manual on off switch, all 110 volts. thanks in advance.

must be too tuff to answer, guess it's time to try and find an electrician.

I'll bet it's this. Both motors are in parallel.
Both switches are in parallel.

Wire the parallel combination of the switch in series with one lead of the motor (BLK preferred.

Wire the line to the free end of the switch and the free end of the motor.

If the motors run too fast then place them in series.

I am assuming 2 connections on the motor.
I am assuming 2 connections on the switch.
I am assuming 2 connections on the t-stat.
White is neutral and should not be switched
Black is hot and should be switched.

We really can't give you a diagram unless there is a little more info. Wire colors on each device.

I am sorry, I don't know what happened. We have one top notch electrician here and some other good people. Since tkrussel came, I have left most of the electrical questions to him. I do still keep an eye on things here. It sounds like you connected the motors in series instead of parallel.

Start with the black wire from the house. It needs to run to a contact on the switch. Run another black wire to a contact on the thermostat. Run black wires from the other thermostat contact to one lead of each motor. To complete the circuit, the other lead on each motor needs to be connected to the white wire from the house. Finally, connect the green or bare ground wire from the house to all the metal housings or switch frame. There may be green screws or a green or bare wire meant for it. If not, use any screw in the housing. Drill a hole and put a screw in it if you have to. Look at what is on the other side before drilling any holes. The old insert may have come from the factory without the safely feature of a ground. They are now required in response to fires and electrocutions.

thanks guys, I was about to give up. On the more info, all devices do have just two wires all white. The motors are exactly the same as the evap. fan on the refrigerator(just had to change it out awhile back. as for power, there is just a power chord with a plug that goes to an outlet beside the fireplace, that cord has a white,black and green. the green one I remembered went to a screw on the frame of the stove. If all this is any help, maybe I'll get it going before winter set in. lol Thanks again.

labman, I followed your directions and it appears to be right. To test, instead of starting a fire can I just jump across the t-stat to make the fans start? thanks again(I miss pa)

Should work. Turning the thermostat might work too.

the t-stat in this case don't move, just stuck in the duct work of the stove, I removed a vent cover and held a lighter near the t-stat and the fans kicked on in just a few seconds, looks like were good to go for winter, thanks much.
